The laughs are reportedly over for five top members of the hacker group LulzSec who were arrested on Tuesday and charged as part of a conspiracy case filed in New York federal court. FoxNews.com reports that the arrests were part of a multinational sting across the United Kingdom, Ireland and the United States on Tuesday morning, and LulzSec leader Hector Xavier Monsegur, who operated online under the alias “Sabu,” provided the Federal Bureau of Investigation with information leading to the arrests.
